(I don’t know who the gamers involved were, but the game was Call of Cthulhu, a tabletop RPG in which the players role-play unlucky characters doomed to face H.P. Lovecraft’s most rugous and unspeakable horrors, losing ever more sanity as they find out about Things Man Was Not Meant to Know. Usually everybody’s characters die or go drooling insane in the first few sessions. It’s a very grim game, which makes this story even funnier by contrast.)
